The data files associated with this paper contain bulk and hydraulic property data
and other hydrologically relevant information. Data files are in tab-delimited text and Microsoft Excel formats. Data files
are divided into information files and measurement data files. Blanks appear in the files where information was unavailable
or a measurement was not made.
